2- It seems i always make ground combat in the same map, don't know if its a known bug or feature. Its one where my chinook lands on the bottom left near a factory or big store, and the ufo is always on the top right of the map.
Yeah this threw me off too. Currently it is the only map that is playable. As the alpha and beta progress, they will add new tilesets and maps to the game. The single map is just for playtesting and working out the bugs.
